How to Build a Marketing Team Without Writing a Single Line of Code with Claude Code

Runbear cofounder Seongwon Lee showed how to build an AI marketing team with Claude Code and Cowork using only Markdown files, no code required.

The setup uses a top-level CMO agent plus specialized sub-agents for content creation, social media, and content calendar management.

Shared documents, memory, .claude/agents, and CLAUDE.md coordinate the agents and automate day-to-day marketing work.

Tools like Ahrefs MCP are connected to support real workflows from writing to social publishing and planning.

The case demonstrates that document-based configuration alone can create practical AI operations for marketing teams.
